WindowsError [error 5] Access is denied

Question

I'm using the killableprocess package (built on top of subprocess) for running processes Whenever I run the "killableprocess.Popen(command)" piece of code in my script I get the following error:

File "killableprocess.py", line 157, in _execute_child
  winprocess.AssignProcessToJobObject(self._job, hp)
File "winprocess.py", line 37, in ErrCheckBool
  raise WinError()
WindowsError [error 5] Access is denied
Exception TypeError: "'NoneType' object is not callable" in <bound method AutoHANDLE.__del__ of <AutoHANDLE object at 0x025D42B0>> ignored

But when I run it from the python interactive console (python 2.6) it works fine. That probably means there are permission issues when I run this from the script, but I don't know how to solve them. I tried running the script from a cmd that I ran as administrator, but it didn't help. Tried looking for similar posts but didn't find any good solution. Hope to find some help here I'm running on Windows, specifically Windows 7 Ultimate x64, if it's any help.

thanks

I solved a similar problem I had by switching to the process directory (I was trying to use inkscape) and it solved my problem

import subprocess
inkscape_dir=r"C:\Program Files (x86)\Inkscape"
assert os.path.isdir(inkscape_dir)
os.chdir(inkscape_dir)
subprocess.Popen(['inkscape.exe',"-f",fname,"-e",fname_png])

Maybe switching to the process directory will work for you too.

What I found when running into this with the subprocess module is that the first entry in 'args' (the first parameter to subprocess.Popen() ) needed to be just the executable name with no path and I needed to set executable in the argument list to the full path of my executable.

app = 'app.exe'
appPath = os.path.join(BIN_DIR, app)

commandLine = [app, 'arg1', 'arg2']
process = subprocess.Popen(commandLine, executable=appPath)

确保您的路径包含可执行文件的名称（inkscape.exe）

Answer 4

Alternatively, if your module doesn't work, you can use the «subprocess» module:

import subprocess, os, time

process = subprocess.Popen("somecommand", shell=True)
n = 0
while True:
    if not process.poll():
        print('The command is running...')
        if n >= 10:
            pid = process.pid()
            os.kill(pid, 9) # 9 = SIGKILL
    else:
        print('The command is not running..')
    n += 1
    time.sleep(1)

您是否指定了传递给Popen可执行文件的完整路径 （ argv的第一项）？
